Greetings all. I am a relative newcomer to the HK world and wanted to solicit some input on a project I am considering. I am trying to build or modify an existing clone that is essentially a G3K but with a 16” barrel, G3K length cocking tube and handguards, and a fixed stock. I guess you could call it a G3 Carbine of sorts. I understand that in practical terms this does not greatly shorten the length of the rifle, but I like the aesthetics of it. I have attached a photo for reference showing what I am trying to build in comparison to a full length G3.
Not looking for anything fancy or super detailed, just something generally meets these specs, works reliably, and doesn’t break the bank.
I am not a gunsmith and do not have the tools to become one. Any work that I do to these guns I would have to have someone else do professionally.
I’ve narrowed it down to three basic options:
-Buy a PTR 91 GI
-Purchase a G3K cocking tube, 16” barrel, and HK33 handguard (painted green)
-Have these professionally installed
Estimated ~$930 for the base rifle, $330 for parts = $1260 plus unknown labor costs
-Is it possible to just shorten the existing barrel and move the front sight, etc. back to accommodate the shorter handguard? (If so, this could cut down the parts cost)
-Buy a PTR 104 KFM4R
-Install a metal trigger group (looks fairly straightforward from the research I’ve done provided you get the correct parts)
-Install a standard G3 stock and HK33 handguards (painted green)
-Have the receiver optics rail ground off
Estimated ~$1310 for the base rifle, ~$175 for parts = $1485 plus the labor to have the optics rails removed
-Buy a G3 parts kit
-Buy a receiver
-Buy a G3K cocking tube, 16” barrel, and HK33 handguard (painted green)
Estimating ~$375 for parts kit, ~$330 for front end assembly, ~$280 for receiver = $985 plus unknown labor costs
Please let me know if I’m overlooking anything here. Would also appreciate recommendations as to places that might be able to do some of this custom work and/or experiences from those who have tried something similar.
